Hornet. I lived in eastern Oregon. It was far from the only case we ever found laying in the street, but I think it's the only Hornet case I've ever found. I probably still have it. Cutest case I've ever seen.
After I had a Hornet for a while, I'm sure a K Hornet would be in the works. Not as "cute", but I love hot-rodding things.
Yep, they are both cute cases! But, the Kilbourn re-shouldered Hornet has a bit more zip than the original.
But the benefits of the shoulder over the original bottleneck cartridge is it stops the horrible brass flow! The original case is good for, perhaps, five reloads before you have to scrap them! Adding the 40* shoulder (and neck sizing) allows for a nearly indefinite case life. If you don't make .223's out of them, that is! As always with this type of thing, YMMV!
